∞ Isa 43:10 Ye [are] my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I [am] he: before me there was no God formed, neither shall there be after me.
You may have been taught that you must 'believe' before you can know God. God says that you may know first. The word for 'believe' is trust. God asks you to trust him after you know that he is God.
